PERCENTAGE MECHANISM FOR COIN-CONTROLLED APPARATUS.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed July 7,1905. Serial No. 268.685.

To all whom it may concern:

Be it known that 1, CHARLES E. YALE, a citizen of the United States,residing at Burlington, in the county of Chittenden and State ofVermont, have invented new and useful Improvements in PercentageMechanism for Coin-Controlled Apparatus, of which the fol' lowingis aspecification.

This invention relates to percentage mechanism for coin controlledapparatus, and one of the principal objects of the same is to providereliable and efficient means for regulating the percentage in a coincontrolled apparatus so that any desired amount over and above the facevalue of the coin deposited maybe delivered.

Another object is to provide a drum with a series of apertures in itsperiphery, and means whereby the area and extent of these apertures maybe increased or diminished in order that the percentage of delivery maybe regulated by means of a set of ejector devices traveling over thesurface of the drum and being actuated when engaged in the apertures.

These and other objects are attained. by means of the constructionillustrated in the accompanying drawing, in Which Figure 1 is a frontelevation of the percentage drum, and showing pawl or dog engagedtherewith. Fig. 2 is an edge view of the drum. Fig. 3 is a centralvertical section of the same.

Referring to the drawing for a more particular description of theinvention, the numeral 1 designates a drum, having a central bearing 2for a shaft, and provided with a series of teeth 3 extending entirelyaround the periphery at one edge thereof. Connected to the drum is aring 4, containing a convolute spring 5, and a friction pawl 6 extendsthrough the periphery of the ring and is adapted to bear upon the springwhen depressed at its end. A series of gear teeth, 7, is formed on theperiphery of the ring 4, and the teeth are omitted at the point at whichthe pawl is pivoted. A ring or disk 8 is held in place within the ring 4to confine the spring 5 within the ring. A ratchet disk 9, having a hub10, around which the spring 5 is wound and to which one end of the sameis secured, is disposed intermediate the drum 1 and the ring 4, and apawl 11, is pivoted at the side of the drum 1 to engage the teeth ofsaid disk. A series of apertures 12, extend from one edge of theperiphery of the drum toward the other, and these apertures are ofdifferent areas in both longitudinal and transverse directions.Adjustable slides 13, are fitted, one to each aperture, and adjustingscrews 14 pass through bosses 15, formed on the slides. When the screwsare turned the slides are mov d outward or inward to expose more or lessarea of the apertures. A series of pawls, one of which, 16, is shown inFig. 1, is adapted to have their noses 17 bear upon the periphery of thedrum 1, and when one of said pawls comes into coincidence with one ofthe apertures 12, the nose 17 engages the same and stops the revolutionof the said drum.

The term percentage mechanism as used in this specification refers tomeans whereby the owner of one of the coin controlled machines of whichthis percentage mechanism forms a part,may adjust the parts so that anydesired percentage over and above the face value of the coin depos itedmay be delivered. To illustrate: If the machine is intended to deliverchecks having a minimum value of five cents in trade at the store wherethe machine is placed, the percentage mechanism described may beadjusted to average a delivery of six checks for twenty-five cents,or-even a larger percentage if desired. But since one of the noses 17 ofthe pawls 16 must engage one of the apertures 12 at each operation ofthe machine, a check is sure to be delivered each time the drum isactuated.

The operation of the invention may be described as follows The drum 1 isgiven an initial impetus by means of the spring and connected mechanism,and is started to spin on its shaft. The noses 17 of the pawls 16 bearon the periphery of the drum and when one of the noses engages one ofthe apertures, the delivery mechanism (not shown) is operated.

From the foregoing it will be understood that the percentage of deliverycan be regulated by the slides, so that checks of differentdenominations may be delivered from the machine, and that thispercentage may be regulated at the wish of the attendant of the machine.

Various'changes may be resorted to in the details of constructionWithout departing from the spirit and scopeof the invention.

Having thus described my invention, what I desire to secure by LettersPatent and claim is a 1. In percentage mechanism for coin controlledapparatus, a drum having a plurality of apertures in its periphery, andadjustable means for varying the areas of said apertures.

2. In a mechanism of the character described, a drum having a series ofapertures of diilerent sizes in its periphery, and means for regulatingthe sizes of said apertures, in combination With paWls or dogs adaptedto engage said apertures and serving as a stop for said drum,substantially as described.

3. In mechanism of the character described, a drum having a series. ofapertures therein, and adjustable slides for covering more or less ofeach aperture, for the purpose set forth.

4. In apparatus of the character described, a spring actuated drumhaving a series of apertures in the periphery thereof, adjustable slidesfor exposing more or less of said apertures, and a series of paWlsadapted to engage said apertures and stop the revolution of said drum.

5. In apparatus of the character described, a drum, having a series ofapertures in the periphery thereof, slides, set screws for adjusting theslides for covering more or less of the apertures, a spring ring, aspring therein, gear teeth on the ring, and pawls, adapted to engagesaid apertures and stop the revolution of the drum, substantially asdescribed.
